HMC970

2 WATT PIN MMIC HIGH ISOLATION

SPDT SWITCH, 8 - 21 GHz

Features

Functional Diagram

General Description

the hMc970 is a broadband high isolation all-shunt

high ip3 design, reflective piN SpDt MMic chip.

covering 8 to 21 Ghz, the switch features 40 dB

isolation and low 1.2 dB isolation loss. the hMc970

is capable of switching 2w of power from 8 to

21 Ghz. the hMc970 operates from a positive

(30mA) supply current and a negative (-10V) supply

voltage and includes on chip bias network, thus

requiring no RF chokes to apply Dc bias. Bias control

signals for the switch consists of a reverse bias vol-

tage of -10V typical for ON state and a forward bias

current of 30 mA for the OFF state.

high isolation: 40 dB

Low insertion Loss: 1.2 dB

All-Shunt Reflective topology

high Linearity: +50 dBm input ip3

compact Die Size: 2.21 x 1.45 x 0.1 mm

Typical Applications

the hMc970 is ideal for:

• telecom infrastructure

• Microwave Radio & VSAt

• Military Radios, Radar & ecM

• Space Systems

• test instrumentation
